(Friday, July 29th 2011) 9:05am PT -- "The Portland International Airport will close out the month of July without a single 90 degree high temperature. This is the first such occurrence in the month of July in nearly 20 years. One has to go back to July of 1993 in order to find another July without a single 90 degree high temperature in Portland. The average temperature at the airport is just 66.3 degrees (through 7/28) which is -1.7 degrees below normal for the month-to-date. Cool onshore flow continues this summer with no heat waves on the horizon anytime soon. Portland's highest temperature so far this entire calendar year is 87 degrees, set on July 6th and again on July 24th. Historically speaking, the average first 90 degree temperature of the year in Portland occurs on June 30th. We are a solid 30 days behind schedule which continues the trend over the past few months.

Let's not forget how beautiful our weather has been. Much of the country is dealing with extreme heat and high air-conditioning bills. It is safe to say many people across the country would gladly trade places with the Northwest. A reminder that the warmest normal high temperature for the year at PDX is 81 degrees. Record highs go up to 107 degrees. I would say 70-85 degrees (where we have mostly been), is just about perfect!
